Is Polysilicone-10 natural?

No. Silicones score 0.00 on this site whatever their side groups, so the plant dimer acid does not change the value.

How we scored it

Silicone copolymer: PDMS with PEG, dimer-acid ester and perfluoroalkyl end groups. Every silicone on this site is 0.00 whatever its side groups, as for Polysilicone-1 to -11 and -15: 0.00.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

A hydroxypropyl-terminated PDMS is ethoxylated and esterified through dilinoleic (dimer) acid to a perfluoroalkyl alcohol; only the dimer acid is natural-origin, from vegetable or tall-oil fatty acids. No alternative route is known.

In plain English

A silicone polymer joined to a polyethylene glycol chain, a fluorinated chain and a fatty dimer acid made from vegetable oil. It is used to control foaming and to condition hair. It is made in a factory, and only the fatty acid part comes from plants.

CosIng definition: Polydimethylsiloxane, methyltrimethylsilyloxy-3-hydroxypropoxysilyl terminated, ethoxylated, diester with perfluoroalkyl hydrogen dilinoleate
